Lag - Disabling Full Screen Optimization

Full screen optimization lets your operating system optimize applications and games that take over the whole screen. It’s part of the Windows 10 Anniversary Update, and it’s on by default. Sometimes it makes things worse, so here’s how you can disable full screen optimization:

  1. Click the Start button start_2.png
  2. Click the Settings icon settings.png
  3. Click the “Gaming” option, which should prompt a window titled “Game bar”
  4. Uncheck “Show game bar when I play full screen games Microsoft has verified”
  5. Close the window

If you want full screen optimization on for other applications, you can disable it for League only:

  1. Right-click the League of Legends icon League.png
  2. Click on Properties
  3. Click on the Compatibility tab
  4. Check “Disable Full Screen Optimizations”
  5. Click OK
  6. Open File Explorer on the taskbar
  7. Go to “C:\Riot Games\League of Legends\RADS\solutions\lol_game_client_sln\releases\
  8. Click into the latest game version folder
  9. Click into the deploy folder
  10. Right-click “League of Legends.exe” League.png
  11. Click on Properties
  12. Click on the Compatibility tab
  13. Check “Disable Full Screen Optimizations”
  14. Click OK

You’ll have to do this after every patch release, so it might be easier overall to disable it through Windows settings if it’s causing problems, and just re-enable it whenever you want to use it.
